FIELD: technological processes.
SUBSTANCE: inventions relate to composite materials used in various fields of technology, in particular in missile, aircraft and mine-torpedo armaments, namely, to feedwell of defense of warhead and to the method of its manufacture. Manufacture of feedwell of heat insulation includes forming blank of the honeycomb core. Blanks of honeycomb core are obtained in form of the required geometry of the feedwell. Subsequently, filler honeycombs are layer-by-layer filled with an inorganic binder with homogenized endothermic additives based on magnesium and calcium carbonates and reinforcing additives based on silicon nanocarbide. Each layer is dried with a stream of hot air. Feedwell with filled honeycombs is placed in convection drying chamber until drying is finished.
EFFECT: increases operational reliability of feedwell.
